similar to: plotting text with very small negative rotation hangs (PR#9301)

Hello I need to plot 3 graphs in a single column; the top two plots have the same title, and I would like it to be written only once, centered horizontally and spanning the two plots. Something like t +------------+ | | i | | | | t +------------+ l +------------+ | | e | | | | 1 +------------+ t

Full_Name: Emmanuel Paradis Version: 2.4.0 OS: Linux Submission from: (NULL) (193.49.41.124) Adding text to a plot makes R freeze if 'srt' is given a very small negative value, eg: plot(1, type = "n") text(1, 1, "some text....", srt = -1e-8) But if 'srt = -1e-6' (or smaller) or 'srt = -1e-19' (or greater), this works. This seems to be OS-dependent:

Is there a way to create a 'bubble plot' in R? For example, if we define the following data frame containing the level of y observed for 5 patients at three time points: time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))

Dear R experts, I am plotting the population of students who live in a city, and in successive circular bands made of the contiguous districts that surround the city. This is a stylized figure, where I specify the area of each successive circle based on the cumulative population of students. I want to compare two sets of concentric circles across different populations - such as 'All

I do not know the precise language to describe the situation. But here it is what I want to do. I need to annotate a graph that contains two or more curves with labels that contain math symbols. The label must go on top of the curve. The problem is that when I annotate the plot, I can see the curve behind the label. Here it is an example using a simple straight line. x<-c(0,1)

Dear All I am trying to perform the below optimization problem, but getting (0.5,0.5) as optimal solution, which is wrong; the correct solution should be (1,0) or (0,1). Am I doing something wrong? I am using R 2.5.0 on Fedora Core 6 (Linux). Thanks in advance, Paul ------------------------------------------------------ myfunc <- function(x) { x1 <- x[1] x2 <- x[2] abs(x1-x2) }

Dears, a way to define x and y positions in plots in relative numbers (e.g in fractions between 0 and 1 referring to relative positions inside the plot region) would really help me. One example I would need this to would be to add text via text() to a plot always at a defined spot, e.g the upper left corner. Until now I always determined maximum x and y values and used those, but defining

The following code isn't working and we can't figure out why.. letters = c("A","B","C","D","E","F","G","H","I","J") numbers = 1:3 for(i in 1:6){ #6 letters for (j in 1:3) { #3 numbers for (k in -1:1) {

Disclaimer: I have read plotmath, but maybe it's too late today: How do I get the two labels to be the same: plot.new() lab =expression(paste("Estimated ", t[50]," from tgv")) text(0.5,0.5,lab) # Should look the same as above. I could not get the substitute right: what = "tgv" lab =expression(paste("Estimated ", t[50]," from ",what))

Hi all, I am using optim() to get estimate for parameter 'a' which will minimize the output of lprob.catch(a) and I got an error message: > optim(2,lprob.catch(x, freq,1, 0.5,0.5, a,- 0.7, 1, -0.7,0.1, 1,0.2,2,1,data.sf.mont)) Error in catch2.fun(k, f1, f2, a, b, A, B, R, n0, av, index.n) : Object "a" not found Why wasn't the initial value of a=2 passed to

Hello R usuer, The code given below superimposes a pie diagram on another plot containing some points. However, I would like to center the pie diagram on the xy location on the plot, but not on the center. is there any way to re-center pic diagram. Any suggestion or better alternative are highly appreciated. Thank you in advance for your help. Regards, Bibke library(visualFields) library(car)

Rotated text for axis labels should be possible with one of par(srt=90) axis(1,at,labels) par(srt=0) or axis(1,at,labels,srt=90) (or similar with crt instead of srt) None of these works in pre0.65 or in 0.64.2 _ platform sparc-sun-solaris2.7 arch sparc os solaris2.7 system sparc,

Hi all, I'm trying to write a MH algorithm in R for a standard normal distribution, I've been trying for a good week or so now with multiple attempts and have finally given up trying to do it on my own as I'm beginning to run out of time for this, would somebody please tell me what is wrong with my latest attempt: n=100 mu=0 sigma=1 lik<-function(theta) exp(((theta-mu)^2)/2*sigma)

Hello, I recently switch over from Splus to R and I have not been able to generate right axis labels that face inwards. This is accomplished in Splus with the command srt=270 but this option is not supported in R. In addition the par argument las=0 or 3 does not rotate the right axis labels. The editor of a journal is demanding that the right axis labels face inwards in the figures I recently

Dear all, I stumbled over a problem recently when trying to use srt with text() on a windows device. What I intended to do was to plot a simple regression line, and to rotate a piece of text such that the text has the same angle as the regression line. However, the text is always plotted in a slightly wrong angle: #### x=1:10 #create arbitrary x and y values y=x*2-rnorm(1:10)

Dear all, In an attempt to draw fill patterns in grid graphics, I have encountered a behavior of grobX that I cannot understand from the documentation. Consider this, library(grid) ## gTree g1 <- gTree(children=gList( rectGrob(0.5,0.5, width=unit(0.8,"npc"), height=unit(2,"cm")), circleGrob(r=0.3)), vp=viewport(0.5,0.5)) ##

Dear R-users moving from Splus to R (under Windows), I notice that command "srt" within a plot in the original Splus code is ignored by R. For example, if a plot something and then include the line of code axis(1, at=Time, labels=Text, srt=45, adj=1) the srt=45 command within the axis() command fails to draw Text at 45 degrees on the x-axis in R but it works properly in Splus. I will

Hello list. Is it possible to use par(srt=45) to rotate text by 45 degrees along the x-axis of a plot. Using: <code> x_names<-c("C57 Nv", "C57 Vacc", "129 Nv", "129 Vacc", "IFNgR Nv", "IFNgR Vacc") par(srt=45) mtext(font=2, x_names, side=1, line=1, at=l, cex=1.2) par(srt=0) </code> doesn't seem to work in R 2.2.0

Sorry about the html-formatted message. Here it is again in plain text. Hello, The function qt returns NaN for degrees of freedom <1. For example: > qt(0.5,0.5) [1] NaN Warning message: In qt(p, df, lower.tail, log.p) : NaNs produced But qt(0.5,0.5) should be 0, since the distribution is symmetric. > pt(0,0.5) [1] 0.5 It actually fails with any value, as long as df<1.
